Method Details

wignerTransform

public static double[][] wignerTransform(double[] doubleData)

Calculate Wigner transform of real data. Will need to take the Hilbert transform and then call the complex function.

Parameters:

doubleData - double array of Wigner data

wignerTransform

public static double[][] wignerTransform(double[] doubleData,
 WignerTransform.WignerUpdate wignerUpdate)

Calculate Wigner transform of real data. Will need to take the Hilber transform and then call the complex function.

Parameters:

doubleData - double array of Wigner data

wignerUpdate - - callback listener which returns every calculated complex line of wigner plot

wignerTransform

public static double[][] wignerTransform(double[] doubleData,
 WignerTransform.WignerUpdate wignerUpdate,
 boolean dump)

Calculate Wigner transform of real data. Will need to take the Hilber transform and then call the complex function.

Parameters:

doubleData - double array of Wigner data

wignerUpdate - - callback listener which returns every calculated complex line of wigner plot

dump - - true to dump data and save memory. If true function will always return null but data will have been passed through wignerUpdate listener.

wignerTransform

public static double[][] wignerTransform(ComplexArray complexData)

Calculate the Wigner transform from data that has already been Hilbert transformed.

Parameters:

complexData -

Returns:

double array of Wigner data

getMaxValue

public static double getMaxValue(double[][] array)

getMinValue

public static double getMinValue(double[][] array)
